BURNER FOR HEATING PURPOSES:

Application led' June 23,

T0 all whom it may cof/wein Be it known that I, BRUNO SIMONIDES, citizenof the Republic of Germany, residing at Mannheim, Germany, have inventedcertain new and useful Improvements in Burners for Heating Purposes,(for which I have filed applications in Germany Mar. 14, 1919, Apr. 11,1919, and Nov. 6, 1919,) of which the following is a specification.

The invention relates to heating burners for liquid and gaseous fuelwith the supply of air or steam as forcing agent. The object of theinvention is to supply the fuel in proportion to the quantity of air orsteam and to mix the fuel in a state of fine division intimately withthe air or the like. 'This-*object is attained by the mechanismillustrated in the drawings.

In the drawings Fig. 1 is a longitudinal section through the burner,Fig. 2 a crosssection along line A-A, Fig. 3 a cross-section along lineB-B and Fig. 4 a cross-section along line C-C of Fig. 1. Fig. 5illustrates a longitudinal section through a detail, Fig. 6 an elevationof a detail, Fig. 7' is a plan of the detail shown in Fig. 6, Fig. 8 across-section along line B- B and Fig.. 9 a cross-section alongrline E-Eof Fig. 5.A Figs. 10-14 show longitudinal sections through slightlymodified apparatus and Fig. 15 a cross-section along lme F-F of Fig. 14.Thelcasing piece 2 forms the burner tube around which a chamber 3 isarranged into which the air-pipe 4 opens. The chamber 3 communicateswith the interior of the burner tube 2 by a series of tangentialpassages arranged. concentrically around it, the said assages consistingof two parts 5 and 7. he portions 5 of the passage are provided in thewall of the burner tube 2 while the portions 7 are located in a sleeve 6which is adapted to be rotated around the tube 2, in order to regulatethe area of the air jets directed into the nozzle portions 5 by thepassage portions 7. In its rear the` burner tube 2 is closed by a cover8. Upon a boss of this cover 8 is-slidably disposed a dishshaped body 9which is adapted to be moved longitudinally by means of an adjustingscrew 10. .At the forward end of the said body 9 are dis sed a series ofconcentric rings 13 provi ed with radial ribs 14 and Specification ofLetters Patent.

vane-like extensions 14. The said rings are maintained in position bymeans of a spindle 12 secured in the centre line of the burner by meansof a cross-pin 11. The forward end of the oil-dish 9 into which oildrips from the rings 13 is formed as an annular shell m which surroundsthe said rings 13. Around the shell an annular space is formed throughwhich a part of the forcing agent may pass to the mouthpiece of theburner. By adjusting the said oil-dish 9, the effect of this portion ofthe forcing agent may beregulated. Into the space surrounded by therings 13 opens the fuel pipe 15 slidably arranged in the VVcoverS, thesaid pipe 15 being provided with fine bores 16 at its extremity. Thetiuel supply-pipe 15 is at 17 provided with a fuel regulator whichconsists of an inlet socket 19, an outlet socketl 20 and a cock plug 21with housing 18. The sockets 19 and 20 are in communication with eachother by means of a passage 22 for the fuel provided.

in the plu-g of thel cock 21, the mouth of the said passage beingrectangular and slightly incl-ined, see Fig. 2, and provided with agoverning element 23 which consists of a slidevalve adapted to'movealong the plug of the cock and provided with an inclined edge 24, Figs.6 and 7, by means of which edge the portl of the socket 20 may becontrolled. The slide-valve 23 is coupled with a piston 27 slidablyarranged in a longitudinal bore 25 of the plug of the cock, the saidpiston 27 being at its upper end furnished with a spindle 28 screwedinto it. For rotating the spindle it is provided with a handle 29 havinga pointer which moves along a scale 30. A key 31 serves for turning thecock plug.

The sleeve or ring valve 6 is adapted to be regulated by turning theplug of the. fuel valve, so that the area of the nozzles 7 may beadjusted simultaneously with the cock. This object is attained by fixingupon the lower ,end of the plug 21 a projection or cam 32 excentricallywhich engages a slot 33 in the sleeve 6.

To enable the fuel to be heated, the fuelpipe 37 with an annular space38 in the mouth-piece 39 of the burner, which may be made in two parts..The portion of the fuel-pipe 15 located within the chamber in a thinlayer and to facilitate its heating. The flat portion of the fuel-pipedivides the chamber 34 in two compartments, see Fig. 8, through whichthe heating agent can pass longitudinally. As forcing agent air ispreferably used which passes to the burner either in consequence of itsnatural buoyancy or is put under pressure by means of a suitable blower.As liquid fuel crude oil, naphtha, tar-oil or the like may be used, theoil flowing from a receptacle by gravity or being forced to the burnerby means of pumps or the like.

The'air enters through the nozzles 7, 5 in the form of broad jets intothe burner tube 2, whirling' around in' a circle. The whirling airengages the vanes 14 and imparts rotary motion to them and consequentlymakes the rings 13 spin around the fuel pipe 15. One part of the airpasses through the rings 13 and carries the oil along with it whichemerges through the perforations 16 at the end ofthe fuel pipe 15 andwhich is spread over the inner surfaces of the rings 13 by the ribs 14ina state of fine division.

By adjusting the sleeve or sliding ringvalve 23 the quantity of the fuelto be introduced is regulated according 'to the effect to be produced bythe burner. For a constant effect of the burner, the position of thering valve 23 remains constant during the use of the burner. The cuttingofi' and the starting of the supply of oil is effected by means of thehandle 31 whereby simultaneously the passages 5, 7 are regulated.

In the constructions illustrated in the Figs. 10, 11 and 12 the plug 21of the cock is coupled with the rotatable ring-valve 6 upon the burnertube 5 by means of a noncircular extension 40, square head or the likewhich is provided with a bore 41 for the reception of the fuel-pipe 15or which itself is adapted to serve ,as fuel-pipe, see Fig. 11, andwhich through a passage 42 communicates with the socket 2O of the cock18.

In the burners illustrated in Figs. 11 and 12, gas under pressure entersthe burner through the pipe or tubular extension 15 and carries the airentering through the ringvalve 6 along into the nozzle-like portion 43of the burner in which the inflammable mixture of gas and air isformed.I By adjusting the cock lug 21 the admission of air and gas isregulated simultaneously as in the preceding constructions. In theburner represented in Fig. 12, a ring disposed around the mouth of thefuel-supply pipe is provided with nozzles 45 for the distribution of thefuel 'and with tubes 46 concentric to the nozzles for the passage of theair. The tubes 46 lead the air into the nozzles 45, through which amixture of air and gas enters into the mouth pieces 43 which arearranged in line and opposite the nozzles 45 and the mouth of which iscovered with wire gauze 47 to prevent back firing.

Existing burners of obsolete construction may be converted into hea-tingburners by applying the described improvements to them, as shown by waylof example in Fig. 13. lith this end in view., the rotary ringvalve 6for regulating the air-supply is arranged upon an extension 2 of theburner Z1 to be improved and the said valve is controlled by theprojection 32 arranged lupon the lower end of the plug of the cock forthe fuel supply engaging the slot 33, so that the supply air and fuel issimultaneously regulated by turning the cock by the aid of the key 31.The larger portion of the fuel pipe 15 is located outside the casing ofthe burner and can easily be adapted to any shape of burner. T he areasof the openings 5 of the inserted pieces 2 are regulated by a disc 48mounted upon the end of an adjusting screw 49 by means of which it ismoved along the openings 5 and cuts off a larger or smaller portion ofthem. Y

In the burner illustrated in Fig. 14, several rings 13 are disposedaround the ribs 14 upon supporting walls 59 arranged in the casing,which rings do not take part in the revolutions 0f the ribs. The ribsl14 are furnished with vanes 14' and joined at one end to a collar 50and at the other end to a collar 51. The collar 50 is joined to a pinterminating into a point and adapted to revolve in a bearing 52 and thecollar 51 is adapted to revolve upon a boss 53 of the cover 8 of theburner, the fuel pipe 15 'passing through said boss in which it may alsorevolve. l:Upon the fuel pipe 15 projections may advantageously beprovided which abut against the ribs 14 so that the fuel pipe mayberevolved by the aid of the ribs 14, if desired. The longitudinal edgesof the ribs 14 are preferably provided with teeth 54. In the mouth piece56 of the burner a cylinder or ring m is supported upon helical ribs 57in line with the rings 13 so that between the cylinder m and the innerwall of the burner mouth-piece 56 spiral passages 58 are produced in theannular space which opens into the mouth of the burner and in whichtwist is imparted to the forcing or propelling agent. In consequence ofthe centrifugal action of the ribs 14 propelled by the. vanes 14', thefuel issuinfr through perforations in the end of the fuel pipe is finelydistributed over the ribs and passes especially from the points or teeth54 on to the .inner surfaces of the rings 13, so that the air passingthrough the rings 13 and carries the fuel distributed over the rings andsuspended in the ring spaces along with it. One or more of the rings 13may be joined to the ribs 14 so that they rotate with them while therest remain stationary. I
